How does an automatic soap dispenser work

Passive infrared sensor

Infrared sensors detect infrared energy that is emitted by one's body heat. When hands are placed in the proximity of the sensor, the infrared energy quickly fluctuates. This fluctuation triggers the pump to activate and dispense the designated amount of soap.

How much is an automatic soap dispenser

The automatic soap dispenser generally costs about 300 yuan per unit, and the product uses infrared automatic induction technology to receive and transmit signals. It can automatically receive the signal to turn on the switch of the soap dispenser when the person reaches out the hand, so that the product works to spray soap or foam. Product work has two working modes: automatic setting time and random time. At present, many soap dispensers adopt the form of supplying soap or foam at a set time.
